There is a fuse holder on the light fitting marked nearby as .8 A MAX

The problem is that the fuse keeps blowing. I'm replacing the fuse with
ones marked as 8 mA fast-blow - then I turn on the light and it seems
to work, but on the 2nd or 3rd turn of the main light switch it blows
again.

Well, 0.8 Amp is 800 mA, and you'd not want fast blow for this application
anyway. Anti-surge would be more like it.

If it really is 0.8 amp this must be the mains input - 0.8 amp at 12 volts
is about 10 watts.
